A study on the association of various morphological traits through correlation and path co-efficient analysis in gladiolus showed that, plant height, spike length, number of florets open at one time, floret length, weight of daughter corm and rachis length had positive and significant correlations with maximum direct effect on number of florets per spike. While leaf number, floret diaf'!1eter and spike length though had positive significant correlations, they exhibited maximum indirect effects. Spike length had maximum direct effect with positive and significant correlations on plant height and rachis length. But, number of leaves per shoot, floret length, number of florets open at one time, spike weight and equatorial corm diameter had maximum indirect effects with significant and positive correlations. Floret length, plant height, spike weight, rachis length and number of florets open at one time exhibited positive and significant correlations with maximum direct effects on floret diameter while spike length and number offlorets perspike though had positive and significant correlations exhibited maximum indirect effects.
